Description

Technical Field

[0001] The present invention relates to a feeding device, and in particular, to a material transfer mechanism. Background Art

[0002] At present, sewing equipment for fabrics usually adopts a form of combining a sewing machine with a fabric placement board. That is, the sewing machine responsible for main processing is installed on the fabric placement board. A relatively large-area fabric placement board can be set. An operator can place the first piece of fabric in this batch flat on the fabric placement board, and manually push the first piece of fabric into the sewing head position of the sewing machine, and the sewing machine performs sewing processing on this fabric.

[0003] To solve the problem of purely manually transferring fabrics, some manufacturers use, for example, a liftable pressing plate to press the fabric block that has been flatly placed on the fabric placement board, and then rely on other driving structures to drive the pressing plate to move horizontally until the pressing plate drags the fabric to the sewing head position of the sewing machine for processing.

[0004] Although the above structure can solve the problem of manually dragging fabrics in the first step, but if only relying on the simple cooperation of a single driving structure and the pressing plate, even if the first piece of fabric is automatically dragged to the sewing head position of the sewing machine by the pressing plate for sewing, and the operator has flatly placed the second piece of fabric on the fabric placement board, since the pressing plate is still driving the first piece of fabric for feeding at this time, it cannot timely drag away the second piece of fabric that has been flatly placed. In the experiment of one person managing multiple machines, there is still an obvious room for improvement in the processing efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a material transfer mechanism, and its processing efficiency is further improved.

[0006] To solve the above technical problems, the technical solution of the present invention is: A material transfer mechanism includes a frame, on which a material processing part and a material placement platform are installed. There are a placement area and a transfer area on the material placement platform, and the material processing part is located on one side of the transfer area; It further includes a first material transfer part and a second material transfer part; The first material transfer part includes a first transfer frame, a first longitudinal driving member, a first lifting plate, and a first lifting driving member. The first transfer frame is installed on the frame. The first lifting plate is located above the material placement platform. The first lifting driving member is used to drive the first lifting plate to perform up and down lifting movements. The first longitudinal driving member is installed on the first transfer frame, and the first longitudinal driving member drives the first lifting driving member to move back and forth between the placement area and the transfer area; The second material transfer unit includes a second lateral drive, a second transfer rack, a second lifting plate, and a second lifting drive. The second lateral drive is used to drive the second transfer rack to move closer to or away from the material processing unit. The second lifting plate is located above the transfer area, and the second lifting drive is installed on the second transfer rack and is used to drive the second lifting plate to move up and down.

[0007] Through the above technical solution, the material to be processed is first laid flat in the placement area. The first lifting drive drives the first lifting plate to move downward, and the first lifting plate presses the material to be processed onto the material placement platform. The first longitudinal drive drives the first lifting drive to move, and the first lifting plate transfers the material located in the placement area to the transfer area; during this process, the operator can lay the second piece of material to be processed flat in the placement area. The end of the material located in the transfer area is already on the material processing unit. The second lifting member drives the second lifting plate to move downward, and the second lifting plate presses the material located in the transfer area. When the material processing unit processes the material, the second lateral drive drives the second transfer rack to move closer to the material processing unit, and at the same time, the second lifting plate can gradually and stably transfer the material into the material processing unit for processing. During the above material transfer process, the operator only needs to continuously feed the material. The first material transfer unit only needs to be responsible for transferring the material from the placement area to the transfer area, and the subsequent feeding action is continued by the independent second material transfer unit. The first material transfer unit can quickly return to the placement area. With this setting, it is more suitable for the use scenario of one person managing multiple machines, and the processing efficiency is significantly improved.

[0008] Preferably, the first transfer rack is slidably and positionally connected to the frame, and the sliding direction of the first transfer rack is parallel to the sliding direction of the second transfer rack.

[0009] Through the above technical solution, before the processing starts, the position of the first transfer rack can be pushed, so as to control the distance between the first lifting plate and the material processing unit, and adapt to the material transfer requirements of more sizes.

[0010] Preferably, a positioning edge is provided at the placement area of the material placement platform.

[0011] Through the above technical solution, when the operator lays the material flat in the placement area, only by abutting the side of the material against the positioning edge, the positioning requirement of the whole material can be completed. The placement accuracy is high and the operation is convenient.

[0012] Preferably, the positioning edge includes a horizontal strip and a vertical strip. The horizontal strip is parallel to the sliding direction of the second transfer rack, and the horizontal strip and the vertical strip are perpendicular to each other.

[0013] Through the above technical solution, two adjacent edges of the material in the placement area can directly abut against the transverse baffle and the longitudinal baffle, thereby completing the transverse positioning and longitudinal positioning of the material, and further improving the positioning accuracy.

[0014] Preferably, an operation station area is provided on one side of the frame. The operation station area is located on the side of the placement area away from the transfer area. An infrared detection device and a control unit are provided on the material placement platform; The infrared detection device is installed between the placement area and the operation station area. The infrared detection device is used to detect whether the operator's hand is located between the placement area and the operation station area. The control unit is electrically connected to the infrared detection device and the first lifting drive member; when the infrared detection device detects that the operator's hand is in the area between the placement area and the operation station area, the control unit controls the first lifting drive member to continuously lift and does not perform a pressing operation.

[0015] Through the above technical solution, when the operator's hand is in the detection area of the infrared detection device, the control unit controls the first lifting drive member to continuously lift and does not perform a pressing operation, so as to avoid accidental crushing of the operator's hand by the first lifting plate and improve the operation safety.

[0016] Preferably, when the material is transferred to the transfer area by the first material transfer part, one end of the material enters the material processing part; The second lifting plate of the second material transfer part is used to press one end of the material in the transfer area away from the material processing part or to press the middle position of the material.

[0017] Through the above technical solution, during the actual sewing process, the threading action of the sewing head on the fabric will inevitably cause a certain amount of wrinkling deformation of the fabric itself. There is also a feed dog structure inside the sewing machine. Although a large-area pressing plate can generate a relatively stable positioning and pressing force on the fabric, combined with the deformation of the fabric during the sewing process by the feed dog inside the sewing machine, it is easy for the entire fabric to deviate when forced. Therefore, the second lifting plate only needs to press the end of the material in the transfer area, and the entire material can be stably transferred into the material processing part without easy deviation, with extremely high material transfer efficiency and stability; In addition, the middle position of the material can also be pressed by the second lifting plate first. After part of the material is processed by the material processing part, the second lifting plate can be gradually transferred to one end of the material away from the material processing part, which also has extremely high material transfer efficiency and stability.

[0018] Preferably, the shape of the second lifting plate is a long strip plate, and the length direction of the second lifting plate is parallel to the sliding direction of the first lifting drive member.

[0019] Through the above technical solution, the second lifting plate actually only produces extrusion pressure on the end of the material away from the material processing part. Then the second lifting plate is in the shape of a long strip, and the length direction of the second lifting plate is parallel to the sliding direction of the first lifting drive member, which can produce a more stable pressing force on the material at this position.

[0020] Preferably, the second lifting plate includes a fixed plate and a movable plate. The fixed plate is fixedly connected to the driving end of the second lifting drive member. The movable plate is located below the fixed plate. The movable plate and the fixed plate are slidably connected via a guide column. An elastic member is also connected between the movable plate and the fixed plate.

[0021] Through the above technical solution, when the second lifting plate is pressed down to one side of the material placement platform, the material will be squeezed between the second lifting plate and the material placement platform. The movable plate and the fixed plate cooperate with each other through the guide columns and elastic parts, which can not only produce an elastic squeezing effect on the material, but also significantly improve the stability of the material pressing.

[0024] The following is combined with Figure 1 -Attached Figure 3 , the specific implementation methods of the present invention are further described in detail to make the technical solution of the present invention easier to understand and grasp.

[0025] A material transfer mechanism comprises a frame 1, on which a material processing unit 2 and a material placement platform 3 are mounted. The material processing unit 2 can be a sewing machine.

[0026] The material placement platform 3 is provided with a placement area 4 and a transfer area 5, and the material processing unit 2 is located on one side of the transfer area 5. Figure 2For reference, the material processing section 2 is located at the left side of the transfer area 5 .

[0027] The first material transfer part 6 is installed on the frame 1. The first material transfer part 6 includes a first transfer frame 61, a first longitudinal drive member 62, a first lifting plate 63, and a first lifting drive member 64. The first transfer frame 61 is installed on the frame 1, and the first lifting plate 63 is located above the material placement platform 3. The first lifting drive member 64 can be an electric cylinder or a pneumatic cylinder, and the first lifting drive member 64 is used to drive the first lifting plate 63 to move up and down. The first longitudinal drive member 62 is installed on the first transfer frame 61, and the first longitudinal drive member 62 drives the first lifting drive member 64 to move back and forth between the placement area 4 and the transfer area 5, so that the first lifting plate 63 can move back and forth between the placement area 4 and the transfer area 5 synchronously.

[0028] A second material transfer part 7 is also installed on the frame 1. The second material transfer part 7 includes a second transverse driving member 71, a second transfer frame 72, a second lifting plate 73, and a second lifting driving member 74. The second lifting plate 73 is located above the transfer area 5. The second lifting driving member 74 can be an electric cylinder or a pneumatic cylinder. The second lifting driving member 74 is installed on the second transfer frame 72 and is used to drive the second lifting plate 73 to move up and down. The second transverse driving member 71 is installed on the frame 1 and is used to drive the second transfer frame 72 to move closer to or away from the material processing part 2, thereby causing the second lifting plate 73 to move closer to or away from the material processing part 2 synchronously.

[0029] The first longitudinal driving member 62 and the second transverse driving member 71 can both adopt common driving forms such as a combination of a motor, a synchronous wheel, and a synchronous belt, or a combination of a motor and a screw, or a common driving form of a cylinder.

[0030] When the material is transferred to the transfer area 5 by the first material transfer part 6, one end of the material enters the material processing part 2; the second lifting plate 73 of the second material transfer part 7 is used to press the end of the material in the transfer area 5 away from the material processing part 2 or to press the middle of the material. In this way, the second lifting plate 73 can not only push the material to move to the side of the material processing part 2, but also give the material in the processing state a certain degree of freedom of movement, so that the material processing quality is better.

[0031] The second lifting plate 73 is in the shape of a long strip plate, and the length direction of the second lifting plate 73 is parallel to the sliding direction of the first lifting driving member 64. The second lifting plate 73 includes a fixed plate 731 and a movable plate 732. The fixed plate 731 is fixedly connected to the driving end of the second lifting driving member 74. The movable plate 732 is located below the fixed plate 731. The movable plate 732 is slidably connected to the fixed plate 731 through a guide post 11. A resilient member 12 is also connected between the movable plate 732 and the fixed plate 731. The resilient member 12 is a spring.

[0032] The first transfer rack 61 is slidably connected to the frame 1, and the sliding direction of the first transfer rack 61 is parallel to the sliding direction of the second transfer rack 72 to adapt to the transfer of materials of more sizes. Before the mechanism is started, the first transfer rack 61 can first slide to a specified position and then be positioned at the specified sliding position.

[0033] A positioning stop edge 8 is provided at the placement area 4 of the material placement platform 3. The positioning stop edge 8 includes a transverse stop bar 81 and a longitudinal stop bar 82. The transverse stop bar 81 is parallel to the sliding direction of the second transfer rack 72, and the transverse stop bar 81 and the longitudinal stop bar 82 are perpendicular to each other.

[0034] An operation station area 9 is provided on one side of the frame 1. The operation station area 9 is located on the side of the placement area 4 away from the transfer area 5. An infrared detection device 10 and a control unit are provided on the material placement platform 3. The infrared detection device 10 is installed between the placement area 4 and the operation station area 9. The infrared detection device 10 is used to detect whether the operator's hand is between the placement area 4 and the operation station area 9. The control unit is electrically connected to the infrared detection device 10 and the first lifting driving member 64. When the infrared detection device 10 detects that the operator's hand is in the area between the placement area 4 and the operation station area 9, the control unit controls the first lifting driving member 64 to continuously lift and does not perform a pressing operation.

[0035] Both the first lifting driving member 64 and the second lifting driving member 74 can be lifting cylinders.

[0036] The above infrared detection device 10 includes a pair of infrared emitting tubes and an infrared receiving tube, which are oppositely arranged on both sides of the working area to form a specific detection area.

[0037] When an object enters the detection area, the infrared rays emitted by the infrared emitting tube will be blocked, and the intensity of the infrared signal received by the infrared receiving tube will change. The infrared receiving tube transmits the received signal to the signal processing module of the control unit.

[0038] The signal processing module analyzes and processes the received signal to determine whether a human hand enters the detection area. If the determination result is that a human hand enters the detection area, the signal processing module sends a control signal to the drive module.

[0039] According to the received control signal, the drive module controls the first lifting drive member 64 to continuously lift without performing a pressing-down operation. The first lifting drive member 64 moves synchronously under the control of the drive module to ensure the stability of the operation.

[0040] In practical applications, the detection range and sensitivity of the infrared detection device 10 and the control logic of the control unit can be adjusted according to specific requirements to adapt to different working scenarios.

[0041] Taking fabric as the material to be processed as an example, the operation process of the above material transfer mechanism: according to the overall size of this batch of fabric, adjust the position of the first transfer rack 61, and then position the first transfer rack 61 at this position. The operator stands in the operation station area 9 and spreads the first piece of fabric flat in the placement area 4, and accurately places it in the placement area 4 with the horizontal baffle 81 and the vertical baffle 82 as references. The first lifting drive member 64 drives the first lifting plate 63 to move downward, and the first lifting plate 63 presses the material to be processed on the material placement platform 3. The first longitudinal drive member 62 drives the first lifting drive member 64 to move, and the first lifting plate 63 transfers the material located in the placement area 4 to the transfer area 5. During this process, the operator can spread the second piece of material to be processed flat in the placement area 4. One end of the material located in the transfer area 5 is already on the material processing part 2, and the second lifting drive member 74 drives the second lifting plate 73 to move downward, and the second lifting plate 73 presses the end position of the material located in the transfer area 5. When the material processing part 2 processes the material, the second transverse drive member 71 drives the second transfer rack 72 to move towards the side close to the material processing part 2. At the same time, the second lifting plate 73 can gradually and stably transfer the material into the material processing part 2 for processing.

[0042] Of course, the above are only typical examples of the present invention. In addition, the present invention can also have many other specific implementation manners. Any technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection required by the present invention.
